With great sadness I must report my Octopus has died. I am not sure but I suspect he had been going senile. Lost interest in playing, eating, and spent much more time out in the open but not really doing anything.
I suspect he just wasn't meant to live super long, I'd guestimate he was closer to 1 year then 18 months with a life expectancy of 1 year to 18 months, but of course you never know..
He will be missed but I hope to get something new later this year, maybe another Ceph maybe something else.
